Gamakatsu R18-B Multi-Purpose Hook
A totally radical new hook featuring a matte finish with Nano Smooth Coat, a slick, friction-reducing coating that enhances hook penetration by minimizing resistance.
The R18-B is a true barbless hook, designed from point to eye without simply removing a barb. This unique construction provides superior retention of hooked fish due to its retainer bend shape.
The “R” stands for “retainer bend,” which holds fish significantly better than conventional round bend hooks. Made from 2X heavy Gamakatsu wire, it is ideal for big fish such as trout in tailrace fisheries when using small flies.

Used this hook on a trout fishery with small flies and it held the fish well without breaking. The barbless design made it easier to release, and the hook didn’t snag on vegetation. Good for both catch and release and for keeping fish safe.
Sean Paige –
Felt more secure than regular barbless hooks. The retainer bend stayed in place even when the fish struggled. A bit heavier than expected, but that’s what I needed for larger trout.

The smooth finish made it easy to cast and the hook penetrated well. No issues with fish escaping or the hook breaking. Definitely a reliable choice for tailrace fishing.
